I'm going to say that for Stony you pay $350 if/when you are accepted. I'd hope there aren't any schools sleazy enough to make you pay just to find out if you're accepted or not. Unless they notify you with a really fancy singing telegram.
I will lay out a lengthy example of how the money will flow. Hopefully it will clear things up for whoever graces this thread.
You decide to apply to 5 schools:
Pacific
Uconn
LECOM
Western
Iowa
When you're done with your application and decide it's time to submit, you'll select your 5 schools. Then it's time to pay. You're going to drop
$238 for one of your schools PLUS another
$80 for each additional school. So you will pay
$558 total to AADSAS. You pay it all at once. This money is only for AADSAS. It's their fee to process all the applications and verify transcripts and all that good stuff. Unless you decide to come back and add more schools, you are done paying AADSAS money.
Next, check to see if your schools have secondary applications or application fees or both and when they want these items. These fees are what the school charges for whatever reason. We'll say it's to process your application. Any money will go directly to the school. This information can be found in several places (school websites, ADEA guide, calling the school). I will use this link for my example.

Pacific
Pay
$75 Application fee online
At the Same Time you send ADEA AADSAS material. Don't confuse this with paying AADSAS. They're just telling you that on your own accord, you need to follow the link they give you to pay $75. 'Same Time' just means that you don't want to apply in June and then just sit around for 4 months before you remember to send your fee. Just go do it soon.
Uconn
Send
$75 Application fee
At the Same Time you send ADEA AADSAS material. Similar to Pacific. They have a link to go pay. You just go do it.
LECOM
Send a
$50 Applicaiton fee and complete an electronic supplemental application
Only When an Admission Officer Contacts You. That should be clear. Be aware it might come. But don't do anything until they invite you to do so (if they ever do).
Western
Pay
$60 Application fee
and a Supplemental Application At the Same Time you send AADSAS materials. This is all done on Western's website. Don't confuse this with doing anything inside the AADSAS portal. If you apply to Western, they expect you to just go to their website to complete their supplemntal application and pay their $60 fee. They won't invite you to. You just do it. If you forget and sit around long enough, they might give you a nudge and remind you that your AADSAS application is sitting on their desk doing nothing because you haven't paid or turned in their secondary.
Iowa
Send
$60 Application fee ($100 for international students)
Only When an Admission Officer Contacts You. That's clear. Sit and wait for their invitation to pay the fee.
So once you've paid all that, you've spent
$320 in fees to your schools.
$558 (AADSAS) + $320 (sum of your school fees) = $878
Now you sit tight and hope they invite you to interview so you can spend a lot more money to travel and enjoy their pastries and juice in the lobby.
